United States Department of Defense
–
The Department is the largest employer in the world, with nearly 1.3 million active duty servicemen and women as of 2016. Adding to its employees are over 801,000 National Guardsmen and Reservists from the four services and it is headquartered at the Pentagon in Arlington, Virginia, just outside of Washington, D. C. The Department of Defense is headed by the Secretary of Defense, Military operations are managed by nine regional or functional Unified Combatant Commands. The Department of Defense also operates several joint services schools, including the National Defense University, the history of the defense of the United States started with the Continental Congress in 1775. The creation of the United States Army was enacted on 14 June 1775 and this coincides with the American holiday Flag Day. The Second Continental Congress would charter the United States Navy, on 13 October 1775, today, both the Navy and the Marine Corps are separate military services subordinate to the Department of the Navy. The Preamble of the United States Constitution gave the authority to federal government, to defend its citizens and this first Congress had a huge agenda, that of creating legislation to build a government for the ages. Legislation to create a military defense force stagnated, two separate times, President George Washington went to Congress to remind them of their duty to establish a military. In a special message to Congress on 19 December 1945, the President cited both wasteful military spending and inter-departmental conflicts, deliberations in Congress went on for months focusing heavily on the role of the military in society and the threat of granting too much military power to the executive. The act placed the National Military Establishment under the control of a single Secretary of Defense, the National Military Establishment formally began operations on 18 September, the day after the Senate confirmed James V. Forrestal as the first Secretary of Defense. The National Military Establishment was renamed the Department of Defense on 10 August 1949, under the Department of Defense Reorganization Act of 1958, channels of authority within the department were streamlined, while still maintaining the authority of the Military Departments. Also provided in this legislation was a centralized authority, the Advanced Research Projects Agency. The Act moved decision-making authority from the Military Departments to the Joint Chiefs of Staff and it also strengthened the command channel of the military over U. S. forces from the President to the Secretary of Defense. Written and promoted by the Eisenhower administration, it was signed into law 6 August 1958, because the Constitution vests all military authority in Congress and the President, the statutory authority of the Secretary of Defense is derived from their constitutional authorities. Department of Defense Directive 5100.01 describes the relationships within the Department. The latest version, signed by former Secretary of Defense Robert Gates in December 2010, is the first major re-write since 1987, the Office of the Secretary of Defense is the Secretary and Deputy Secretarys civilian staff. S. Government departments and agencies, foreign governments, and international organizations, OSD also performs oversight and management of the Defense Agencies and Department of Defense Field Activities. OSD also supervises the following Defense Agencies, Several defense agencies are members of the United States Intelligence Community and these are national-level intelligence services that operate under the jurisdiction of the Department of Defense but simultaneously fall under the authorities of the Director of National Intelligence

Creative Commons
–
Creative Commons is an American non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public and these licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, Creative Commons licenses do not replace copyright, but are based upon it. The result is an agile, low-overhead and low-cost copyright-management regime, Wikipedia uses one of these licenses. The organization was founded in 2001 by Lawrence Lessig, Hal Abelson, the first article in a general interest publication about Creative Commons, written by Hal Plotkin, was published in February 2002. The first set of licenses was released in December 2002. In 2003 the Open Content Project, a 1998 precursor project by David A. Wiley, announced the Creative Commons as successor project, matthew Haughey and Aaron Swartz also played a role in the early stages of the project. As of January 2016 there were an estimated 1.1 billion works licensed under the various Creative Commons licenses, as of March 2015, Flickr alone hosts over 306 million Creative Commons licensed photos. Creative Commons is governed by a board of directors and their licenses have been embraced by many as a way for creators to take control of how they choose to share their copyrighted works. Beyond that, Creative Commons has provided institutional, practical and legal support for individuals and groups wishing to experiment, Creative Commons attempts to counter what Lawrence Lessig, founder of Creative Commons, considers to be a dominant and increasingly restrictive permission culture. Lessig describes this as a culture in which creators get to create only with the permission of the powerful, as of 2017, they are Paul Keller, Jonathan Nightingale, Chris Thorne. As of 2015, there are more than 100 affiliates working in over 75 jurisdictions to support, Creative Commons Korea is the affiliated network of Creative Commons in South Korea. In March 2005, CC Korea was initiated by Jongsoo Yoon, the major Korean portal sites, including Daum and Naver, have been participating in the use of Creative Commons licences. In January 2009, the Creative Commons Korea Association was consequently founded as an incorporated association. Since then, CC Korea has been promoting the liberal. Since March 15,2012 he has been detained by the Syrian government in Damascus at Adra Prison, on October 17,2015 Creative Commons Board of Directors approved a resolution calling for Bassel Khartabil release. All current CC licenses require attribution, which can be inconvenient for works based on other works. Critics also worried that the lack of rewards for content producers will dissuade artists from publishing their work, Creative Commons founder Lawrence Lessig countered that copyright laws have not always offered the strong and seemingly indefinite protection that todays law provides

Digital camera
–
A digital camera or digicam is a camera that produces digital images that can be stored in a computer, displayed on a screen and printed. Most cameras sold today are digital, and digital cameras are incorporated into many devices ranging from PDAs, Digital and movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film, however, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound, some digital cameras can crop and stitch pictures and perform other elementary image editing. The history of the camera began with Eugene F. Lally of the Jet Propulsion Laboratory. His 1961 idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts position, unfortunately, as with Texas Instruments employee Willis Adcocks filmless camera in 1972, the technology had yet to catch up with the concept. Steven Sasson as an engineer at Eastman Kodak invented and built the first electronic camera using a charge-coupled device image sensor in 1975, earlier ones used a camera tube, later ones digitized the signal. Early uses were military and scientific, followed by medical. In the mid to late 1990s digital cameras became common among consumers, by the mid-2000s digital cameras had largely replaced film cameras, and higher-end cell phones had an integrated digital camera. By the beginning of the 2010s, almost all smartphones had a digital camera. The two major types of image sensor are CCD and CMOS. A CCD sensor has one amplifier for all the pixels, while each pixel in a CMOS active-pixel sensor has its own amplifier, compared to CCDs, CMOS sensors use less power. Cameras with a small sensor use a back-side-illuminated CMOS sensor, overall final image quality is more dependent on the image processing capability of the camera, than on sensor type. The resolution of a camera is often limited by the image sensor that turns light into that discrete signals. The brighter the image at a point on the sensor. Depending on the structure of the sensor, a color filter array may be used. The number of pixels in the sensor determines the cameras pixel count, in a typical sensor, the pixel count is the product of the number of rows and the number of columns. For example, a 1,000 by 1,000 pixel sensor would have 1,000,000 pixels, final quality of an image depends on all optical transformations in the chain of producing the image

Image scanner
–
Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Mechanically driven scanners that move the document are typically used for large-format documents, a rotary scanner, used for high-speed document scanning, is a type of drum scanner that uses a CCD array instead of a photomultiplier. Non-contact planetary scanners essentially photograph delicate books and documents, all these scanners produce two-dimensional images of subjects that are usually flat, but sometimes solid, 3D scanners produce information on the three-dimensional structure of solid objects. Digital cameras can be used for the same purposes as dedicated scanners, when compared to a true scanner, a camera image is subject to a degree of distortion, reflections, shadows, low contrast, and blur due to camera shake. Resolution is sufficient for less demanding applications, Digital cameras offer advantages of speed, portability and non-contact digitizing of thick documents without damaging the book spine. As of 2010 scanning technologies were combining 3D scanners with digital cameras to create full-color, in the biomedical research area, detection devices for DNA microarrays are called scanners as well. These scanners are high-resolution systems, similar to microscopes, the detection is done via CCD or a photomultiplier tube. Modern scanners are considered the successors of early telephotography and fax input devices and it used electromagnets to drive and synchronize movement of pendulums at the source and the distant location, to scan and reproduce images. It could transmit handwriting, signatures, or drawings within an area of up to 150 x 100mm, Édouard Belins Belinograph of 1913, scanned using a photocell and transmitted over ordinary phone lines, formed the basis for the AT&T Wirephoto service. In Europe, services similar to a wirephoto were called a Belino and it was used by news agencies from the 1920s to the mid-1990s, and consisted of a rotating drum with a single photodetector at a standard speed of 60 or 120 rpm. They send a linear analog AM signal through standard telephone lines to receptors. Color photos were sent as three separated RGB filtered images consecutively, but only for special events due to transmission costs, Drum scanners capture image information with photomultiplier tubes, rather than the charge-coupled device arrays found in flatbed scanners and inexpensive film scanners. Modern color drum scanners use three matched PMTs, which red, blue, and green light, respectively. Light from the artwork is split into separate red, blue. Photomultipliers offer superior dynamic range and for this reason drum scanners can extract more detail from very dark areas of a transparency than flatbed scanners using CCD sensors. The smaller dynamic range of the CCD sensors, versus photomultiplier tubes, can lead to loss of shadow detail, while mechanics vary by manufacturer, most drum scanners pass light from halogen lamps though a focusing system to illuminate both reflective and transmissive originals. The drum scanner gets its name from the clear acrylic cylinder, depending on size, it is possible to mount originals up to 20x28, but maximum size varies by manufacturer. One of the features of drum scanners is the ability to control sample area

Free software
–
The right to study and modify software entails availability of the software source code to its users. This right is conditional on the person actually having a copy of the software. Richard Stallman used the existing term free software when he launched the GNU Project—a collaborative effort to create a freedom-respecting operating system—and the Free Software Foundation. The FSFs Free Software Definition states that users of software are free because they do not need to ask for permission to use the software. Free software thus differs from proprietary software, such as Microsoft Office, Google Docs, Sheets, and Slides or iWork from Apple, which users cannot study, change, freeware, which is a category of freedom-restricting proprietary software that does not require payment for use. For computer programs that are covered by law, software freedom is achieved with a software license. Software that is not covered by law, such as software in the public domain, is free if the source code is in the public domain. Proprietary software, including freeware, use restrictive software licences or EULAs, Users are thus prevented from changing the software, and this results in the user relying on the publisher to provide updates, help, and support. This situation is called vendor lock-in, Users often may not reverse engineer, modify, or redistribute proprietary software. Other legal and technical aspects, such as patents and digital rights management may restrict users in exercising their rights. Free software may be developed collaboratively by volunteer computer programmers or by corporations, as part of a commercial, from the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which was typically public domain software. Software was commonly shared by individuals who used computers and by manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, SHARE, were formed to exchange of software. As software was written in an interpreted language such as BASIC. Software was also shared and distributed as printed source code in computer magazines and books, in United States vs. IBM, filed January 17,1969, the government charged that bundled software was anti-competitive. While some software might always be free, there would henceforth be an amount of software produced primarily for sale. In the 1970s and early 1980s, the industry began using technical measures to prevent computer users from being able to study or adapt the software as they saw fit. In 1980, copyright law was extended to computer programs, Software development for the GNU operating system began in January 1984, and the Free Software Foundation was founded in October 1985

Data storage
–
A data storage device is a device for recording information. A storage device may hold information, process information, or both, a device that only holds information is a recording medium. Devices that process information may either access a separate portable recording medium or a permanent component to store, Electronic data storage requires electrical power to store and retrieve that data. Most storage devices that do not require vision and a brain to read data fall into this category, electromagnetic data may be stored in either an analog data or digital data format on a variety of media. Most electronically processed data storage media are considered permanent storage, that is, in contrast, most electronically stored information within most types of semiconductor microcircuits are volatile memory, for it vanishes if power is removed.

Blog
–
A blog is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries. Posts are typically displayed in chronological order, so that the most recent post appears first. Until 2009, blogs were usually the work of an individual, occasionally of a small group. In the 2010s, multi-author blogs have developed, with posts written by large numbers of authors, MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other microblogging systems helps integrate MABs, Blog can also be used as a verb, meaning to maintain or add content to a blog. In the 2010s, the majority are interactive Web 2.0 websites, allowing visitors to leave online comments, in that sense, blogging can be seen as a form of social networking service. Indeed, bloggers do not only produce content to post on their blogs, however, there are high-readership blogs which do not allow comments. Many blogs provide commentary on a subject or topic, ranging from politics to sports. Others function as more personal online diaries, and others function more as online brand advertising of an individual or company. A typical blog combines text, digital images, and links to blogs, web pages. The ability of readers to leave publicly viewable comments, and interact with other commenters, is an important contribution to the popularity of many blogs, however, blog owners or authors often moderate and filter online comments to remove hate speech or other offensive content. Most blogs are primarily textual, although focus on art, photographs, videos, music. In education, blogs can be used as instructional resources and these blogs are referred to as edublogs. Microblogging is another type of blogging, featuring very short posts, on 16 February 2011, there were over 156 million public blogs in existence. On 20 February 2014, there were around 172 million Tumblr and 75.8 million WordPress blogs in existence worldwide, according to critics and other bloggers, Blogger is the most popular blogging service used today. However, Blogger does not offer public statistics, Technorati lists 1.3 million blogs as of February 22,2014. The term weblog was coined by Jorn Barger on 17 December 1997, the short form, blog, was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog Peterme. com in April or May 1999. Shortly thereafter, Evan Williams at Pyra Labs used blog as both a noun and verb and devised the term blogger in connection with Pyra Labs Blogger product, in the 1990s, Internet forum software, created running conversations with threads

Skype
–
Skype is an instant messaging app that provides online text message and video chat services. Users may transmit both text and video messages and may exchange digital documents such as images, text, Skype operate based on a freemium model. Much of the service is free, but Skype Credit or a subscription is required to call a landline or a phone number. At the end of 2010, there were over 660 million worldwide users, at one point in February 2012, there were thirty four million users concurrently online on Skype. In September 2005, eBay acquired Skype for $2.6 billion, Microsoft bought Skype in May 2011 for $8.5 billion. Skype division headquarters are in Luxembourg but most of the development team and 44% of all the employees are still situated in Tallinn and Tartu. Skype allows users to communicate over the Internet by voice using a microphone, by using a webcam. Skype-to-Skype calls to other users are free of charge, while calls to landline telephones, Skype originally featured a hybrid peer-to-peer and client–server system. Skype has been powered entirely by Microsoft-operated supernodes since May 2012, the 2013 mass surveillance disclosures revealed that Microsoft had granted intelligence agencies unfettered access to supernodes and Skype communication content. The name for the software is derived from Sky peer-to-peer, which was abbreviated to Skyper. However, some of the names associated with Skyper were already taken. Dropping the final r left the current title Skype, for domain names were available. Skype was founded in 2003 by Niklas Zennström, from Sweden, the Skype software was created by Estonians Ahti Heinla, Priit Kasesalu, and Jaan Tallinn. The first public version was released on 29 August 2003. In June 2005, Skype entered into an agreement with the Polish web portal Onet. pl for an offering on the Polish market. On 10 May 2011, Microsoft Corporation acquired Skype Communications, S. à r. l for US$8.5 billion, the company was incorporated as a division of Microsoft, which acquired all Its technologies with the purchase. This was completed on 13 October 2011 and this app became downloadable from the Windows Store when the new OS launched on 26 October 2012. When the company introduced Office 2013 on 27 February 2013, it was announced that 60 Skype world minutes per month would be included in Office 365 consumer plans, on 11 November 2014, Microsoft announced that in 2015 Lync would be replaced by Skype for Business

Derivative work
–
In copyright law, a derivative work is an expressive creation that includes major copyright-protected elements of an original, previously created first work. The derivative work becomes a second, separate work independent in form from the first, the transformation, modification or adaptation of the work must be substantial and bear its authors personality to be original and thus protected by copyright. Translations, cinematic adaptations and musical arrangements are common types of derivative works, most countries legal systems seek to protect both original and derivative works. They grant authors the right to impede or otherwise control their integrity, derivative works and their authors benefit in turn from the full protection of copyright without prejudicing the rights of the original works author. An extensive definition of the term is given by the United States Copyright Act in 17 U. S. C. A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a “derivative work”. The copyright in such work is independent of, and does not affect or enlarge the scope, duration, ownership, or subsistence of and this previously published material makes the work a derivative work under the copyright law. To be copyrightable, a work must be different enough from the original to be regarded as a new work or must contain a substantial amount of new material. Making minor changes or additions of little substance to a work will not qualify the work as a new version for copyright purposes. The new material must be original and copyrightable in itself, titles, short phrases, and format, for example, are not copyrightable. The statutory definition is incomplete and the concept of work must be understood with reference to explanatory case law. French law prefers the term œuvre composite although the term œuvre dérivée is sometimes used and it is defined in article L 113-2, alinea 2 of the Intellectual Property Code as the new work in which a pre-existing work without the collaboration of its author. The Court of Cassation has interpreted this statue as requiring two distinct inputs at different points in time, the Court of Justice of the European Union in 2010 decided on a matter of derivative works in Systran v. European Commission. For copyright protection to attach to a later, allegedly derivative work and it cannot be a rote, uncreative variation on the earlier, underlying work. The latter work must contain sufficient new expression, over and above that embodied in the work for the latter work to satisfy copyright law’s requirement of originality. In Durham Industries, Inc. v. Tomy Corp. and earlier in L. Batlin & Son, the Second Circuit held that a derivative work must be original relative to the underlying work on which it is based. Otherwise, it cannot enjoy copyright protection and copying it will not infringe any copyright of the work itself. The Batlin case rested on the copyrightability of an Uncle Sam toy bank and these toys have Uncle Sams extended arm and outstretched hand adapted to receive a coin, when the user presses a lever, Uncle Sam appears to put the coin into a carpet bag

Venn diagram
–
A Venn diagram is a diagram that shows all possible logical relations between a finite collection of different sets. These diagrams depict elements as points in the plane, and sets as regions inside closed curves, a Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. In Venn diagrams the curves are overlapped in every possible way and they are thus a special case of Euler diagrams, which do not necessarily show all relations. Venn diagrams were conceived around 1880 by John Venn and they are used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics and computer science. A Venn diagram in which in addition the area of each shape is proportional to the number of elements it contains is called an area-proportional or scaled Venn diagram and this example involves two sets, A and B, represented here as coloured circles. The orange circle, set A, represents all living creatures that are two-legged, the blue circle, set B, represents the living creatures that can fly. Each separate type of creature can be imagined as a point somewhere in the diagram, living creatures that both can fly and have two legs—for example, parrots—are then in both sets, so they correspond to points in the region where the blue and orange circles overlap. That region contains all such and only living creatures. Humans and penguins are bipedal, and so are then in the circle, but since they cannot fly they appear in the left part of the orange circle. Mosquitoes have six legs, and fly, so the point for mosquitoes is in the part of the circle that does not overlap with the orange one. Creatures that are not two-legged and cannot fly would all be represented by points outside both circles, the combined region of sets A and B is called the union of A and B, denoted by A ∪ B. The union in this case contains all living creatures that are either two-legged or that can fly, the region in both A and B, where the two sets overlap, is called the intersection of A and B, denoted by A ∩ B. For example, the intersection of the two sets is not empty, because there are points that represent creatures that are in both the orange and blue circles. They are rightly associated with Venn, however, because he comprehensively surveyed and formalized their usage, Venn himself did not use the term Venn diagram and referred to his invention as Eulerian Circles. Of these schemes one only, viz. that commonly called Eulerian circles, has met with any general acceptance, the first to use the term Venn diagram was Clarence Irving Lewis in 1918, in his book A Survey of Symbolic Logic. Venn diagrams are similar to Euler diagrams, which were invented by Leonhard Euler in the 18th century. Baron has noted that Leibniz in the 17th century produced similar diagrams before Euler and she also observes even earlier Euler-like diagrams by Ramon Lull in the 13th Century. In the 20th century, Venn diagrams were further developed, D. W. Henderson showed in 1963 that the existence of an n-Venn diagram with n-fold rotational symmetry implied that n was a prime number
